Deutsche Bundesbank — Expectations database (BBUMF)
The BBUMF dataflow is an official time series dataset published by the Deutsche Bundesbank, covering economic and price expectations data for Germany. It is accessible through the Bundesbank's SDMX 2.1 REST API, with a single endpoint offering data in XML (SDMX-ML), CSV, or JSON formats. Users can retrieve specific series using key paths, and refine results with startPeriod, endPeriod, or lastNObservations filters. The dataset is freely accessible without authentication, making it suitable for economic analysis and research involving inflation expectations and related price indicators.Expectations database (BBUMF) — official time series from the Deutsche Bundesbank, published as the BBUMF dataflow over SDMX 2.1 REST. One endpoint serves XML (SDMX-ML), CSV (?format=csv) and JSON (?format=json); extract exactly the series you need with a key path and startPeriod / endPeriod / lastNObservations filters.
